Washington, Sept 19 (ANI): Britney Spears will have to undergo periodic random drug tests to convince the family court system that she is fit enough to take care of her kids.

Court documents show that the troubled singer will have to take two tests a week to ensure that she gets to keep joint custody of her young sons - Sean Preston and Jayden James.

The order was handed down by Los Angeles Superior Court Commissioner Scott M. Gordon who reportedly made the decision after Tony Barretto, a former minder of the singer testified that she had taken drugs, and walked around naked in front of her kids.

"Based on the evidence presented the Court finds that there is a habitual, frequent and continuous use of controlled substances by [Spears]," E! Online quoted the documents, as stating.

According to other documents that were recently unsealed, Spears and ex husband Kevin Federline have also agreed to let the other know if one is planning to leave the state with the kids, refrain from using corporal punishment to discipline their kids, not consume any alcohol or nonprescription drugs at least 12 hours prior to caring for the kids, as well as attend joint coparenting counselling and complete the county's 'Parenting Without Conflict' program.

Britney and K-Fed have also agreed not to badmouth each other in public or in front of the kids.

Apart from all the things she has to do with Federline, Britney has also been ordered by the court to attend individual counselling at least once a week to address parenting issues.

She will also be meeting a parenting coach who will "observe (her) interaction with the minor children and her parenting skills" at least twice a week for a total of eight hours or more.

The coach will provide lawyers on both sides with written reports, and will appear in court at the ex-couple's next hearing on Nov. 26. (ANI)
